Fading and dingy, perhaps (5)
I believe the answer is:
dying
'fading' is the definition.
(I've seen this in another clue)
'dingy perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'dingy' anagrammed gives 'DYING'.
'and' is the link.
(Other definitions for dying that I've seen before include "Coluring, hair or fabric" , "Failing to get laughs" , "Passing away" , "final" , "Perishing" .)
